|~ Leo as he destroys a desert oasis|
Leonard "Leo" Wong is the father of Amy, the husband of Inez Wong and the secondary antagonist from 2009 movie Into the Wild Green Yonder. Together with his wife he owns the Wong Ranch and the entire western hemisphere of Mars, as well as meddling in Amy's love-life with his wife. He is completely blunt and has very few social skills, he always speaks his mind which always enrages people he doesn't buy off. He teases Amy about being fat. He also makes jokes about how she was fat when she was younger which pressured her into losing weight. He couldn't care less about the environment and possibly endangered species. Wong planned to bulldoze 12% of the milky way for his golf course without any regard to any life he may destroy to do it. It is thanks to him that some parts of Saturn's rings are missing. When he hires Fry as his security guard he starts to give him more affection than Amy, making her believe that he didn't want a daughter and indeed wanted a son.
- In their first appearances, Leo and Inez were shown as able to speak grammatically faultless English in spite of their extreme Asian accents, but this trait later disappeared.
- Leo is one of the few characters in Futurama to possess the "belly bulge" that most Simpsons characters have.
- Leo, along with his wife and daughter, speak Cantonese and English, with Mandarin occasionally slipping in the episode "Proposition Infinity".
